Embodiment 1

[0098] Embodiment 1, pre-harvest freshness of Chrysanthemum

[0099] The cut flowers of Chrysanthemum were used as experimental materials, and the cuttings were used for colonization, followed by conventional planting and cultivation management.

[0100] Chrysanthemum pre-harvest preservative is prepared from sucrose, citric acid, potassium nitrate, ammonium nitrate, magnesium sulfate, and calcium chloride.

[0101] The concentration of each component in the pre-harvest fresh-keeping solution of Xiaochrysanthemum can be A3 or A4:

[0102] A3, sucrose 20g / L; citric acid 0.5g / L; potassium nitrate 2g / L; ammonium nitrate 1.5g / L; magnesium sulfate 0.5g / L; calcium chloride 0.5g / L;

[0103]A4, sucrose 10g / L; citric acid 0.25g / L; potassium nitrate 1g / L; ammonium nitrate 0.75g / L; magnesium sulfate 0.25g / L; calcium chloride 0.25g / L.

[0104] The specific experimental concentration ratio is shown in Table 1, wherein CK is the data of clear water (distilled water) of the blank control g...

Embodiment 2

[0121] Embodiment 2, small chrysanthemum pretreatment preservation

[0122] The postharvest pretreatment liquid of Chrysanthemum is prepared from sucrose, 8-hydroxyquinoline, citric acid, calcium chloride, Tween-20, 6-benzylaminoadenine, and 2,4-dichlorophenoxyacetic acid. The specific concentration setting is shown in Table 2, wherein CK is the data of the control group clear water (distilled water).

[0123] Table 2 Concentration settings of postharvest pretreatment solution of control group and different Chrysanthemum chrysanthemum

[0124]

[0125] Among them, individual drug preparation methods:

[0126] 1. 6-benzylaminoadenine: Add a small amount of 40% NaOH solution dropwise into 6-benzylaminoadenine to dissolve it completely, and gradually add distilled water at room temperature to dilute.

[0127] 2. 2,4-Dichlorophenoxyacetic acid: Add a small amount of absolute ethanol dropwise into 2,4-dichlorophenoxyacetic acid, stir while dripping to dissolve completely, then...

Embodiment 3

[0136] Embodiment 3, small chrysanthemum vase preservation

[0137] The small chrysanthemum vase preservative is prepared from sucrose, Tween-20, 8-hydroxyquinoline, citric acid and calcium chloride.

[0138] Specifically, as shown in Table 3, the data C1, C3, C4 and CK of the different experimental groups of the chrysanthemum vase fresh-keeping solution are the data of the blank control group of clear water (distilled water), and the data of the control group C2 and C5.

[0139] Table 3 Different concentration settings and control group data of chrysanthemum bottle cutting fresh-keeping solution

[0140]

[0141] Harvesting and processing: select plants with fresh leaves, no damage to flower buds, and no damage to flower branches. Process the flower branches into a length of 65 cm, remove the lower 25 cm leaves, and make 10 branches into a handful.

[0142] Water absorption: Put the cut chrysanthemums into water tanks, add 2.5L of clear water to each bucket, and keep the ...

Abstract

The invention discloses a fresh-cut chrysanthemum comprehensive fresh-keeping agent and a fresh-keeping method and application thereof. The fresh-cut chrysanthemum comprehensive fresh-keeping agent set is composed of a) to c) which are independently packaged as follows: a) a chrysanthemum pre-harvest fresh-keeping agent comprises the following components (by mass): 10-20g / L of cane sugar, 0.25-0.5g / L of citric acid, 1-2 g / L of potassium nitrate, 0.75-1.5 g / L of ammonium nitrate, 0.25-0.5 g / L of magnesium sulfate, and 0.25-0.5 g / L of calcium chloride; b) a chrysanthemum post-harvest pretreatment liquid comprises the following components in concentration: 10-20g / L of cane sugar, 75-100 mg / L of 8-hydroxyquinoline, 50-100 mg / L of citric acid, 1-2 g / L of calcium chloride, 1-2 ml / L of tween-20,0.5-1 mg / L of 6-benzylamino adenine, and 0.1-0.2 mg / L of 2, 4-dichlorophenoxyacetic acid; and c) a fresh-cut chrysanthemum flower vase fresh-keeping liquid comprises the following components (by massconcentration): 0-10 g / L of cane sugar, 1 ml / L of tween-20, 0-50 mg / L of 8-hydroxyquinoline, 100 mg / L of citric acid and 0.5-1 g / L of calcium chloride, wherein the mass concentrations of the cane sugar and the 8-hydroxyquinoline are not zero at the same time. The fresh-keeping agent is harmless, simple to prepare and good in fresh-keeping effect.

Description

technical field [0001] The invention relates to a comprehensive fresh-keeping solution for fresh-cut chrysanthemums, a fresh-keeping method and application thereof, and belongs to the technical field of fresh-keeping cut chrysanthemums. Background technique [0002] Ethylene inhibitors are usually used in the fresh-keeping process of fresh flowers (such as lilies), and chrysanthemums are ethylene non-climbing cut flowers. Some studies suggest that ethylene inhibitors are not suitable for the fresh-keeping process of cut chrysanthemums. The current market demand for fresh-cut chrysanthemums is very large, but the aging of fresh-cut chrysanthemums is one of the important factors restricting its storage, transportation and development. The factors affecting postharvest aging of fresh-cut chrysanthemums are very complex, including endogenous material factors such as water, protein, sugar, amino acids, and plant hormones, and exogenous environmental factors such as temperature, h...
